A Constraint Programming Approach to the Hospitals / Residents Problem

An instance I of the Hospitals / Residents problem (HR) involves a set of residents (graduating medical students) and a set of hospitals, where each hospital has a given capacity. The residents have preferences for the hospitals, as do hospitals for residents. A solution of I is a stable matching, which is an assignment of residents to hospitals that respects the capacity conditions and preference lists in a precise way. In this paper we present constraint encodings for HR that give rise to important structural properties. We also present a computational study using both randomly-generated and real-world instances. Our study suggests that Constraint Programming is indeed an applicable technology for solving this problem, in terms of both theory and practice

Porter's Industry Clusters in Irish Indigenous Industry. ESRI WP119. August 1999

Studies by Porter (1990) and others find that competitive and successful industries usually occur in the form of clusters of industries which are linked together through vertical or horizontal relationships. This paper assesses whether the sectors of Irish indigenous industry which look most competitive and successful form such clusters. It is concluded that there is only limited or qualified evidence of Porter-type clusters in Irish indigenous industry but, despite this, there has been a relatively strong competitive performance by most of Irish indigenous industry over the past decade. We also comment on policy implications

Learning 21st century science in context with mobile technologies

The paper describes a project to support personal inquiry learning with handheld and desktop technology between formal and informal settings. It presents a trial of the technology and learning across a school classroom, sports hall, and library. The main aim of the study was to incorporate inquiry learning activities within an extended school science environment in order to investigate opportunities for technological mediations and to extract initial recommendations for the design of mobile technology to link inquiry learning across different contexts. A critical incident analysis was carried out to identify learning breakdowns and breakthroughs that led to design implications. The main findings are the opportunities that a combination of mobile and fixed technology bring to: manage the formation of groups, display live visualisations of student and teacher data on a shared screen to facilitate motivation and personal relevance, incorporate broader technical support, provide context-specific guidance on the sequence, reasons and aims of learning activities, offer opportunities to micro-sites for reflection and learning in the field, to explicitly support appropriation of data within inquiry and show the relation between specific activities and the general inquiry process

Exploring women's experiences, views and understanding of vaginal examinations during intrapartum care:A meta-ethnographic synthesis

Objective: To conduct a systematic review exploring women’s experiences, views and understanding of any vaginal examinations during intrapartum care, in any care setting and by any healthcare professional. Intrapartum vaginal examination is deemed both an essential assessment tool and routine intervention during labour. It is an intervention that can cause significant distress, embarrassment, and pain for women, as well as reinforce outdated gender roles. In view of its widespread and frequently reported excessive use, it is important to understand women’s views on vaginal examination to inform further research and current practice.Design: A systematic search and meta-ethnography synthesis informed by Noblit and Hare (1988) and the eMERGe guidance (France et al. 2019) was undertaken. Nine electronic databases were searched systematically using predefined search terms in August 2021, and again in March 2023. Studies meeting the following criteria: English language, qualitative and mixed-method studies, published from 2000 onwards, and relevant to the topic, were eligible for quality appraisal and inclusion.Findings: Six studies met the inclusion criteria. Three from Turkey, one from Palestine, one from HongKong and one from New Zealand. One disconfirming study was identified. Following both a reciprocal and refutational synthesis, four 3rd order constructs were formed, titled: Suffering the examination, Challenging the power dynamic, Cervical-centric labour culture embedded in societal expectations, and Context of care. Finally, a line of argument was arrived at, which brought together and summarised the 3rd orde rconstructs.Key conclusions and implications of practice: The dominant biomedical discourse of vaginal examination and cervical dilatation as central to the birthing process does not align with midwifery philosophy or women’s embodied experience. Women experience examinations as painful and distressing but tolerate them as they view them as necessary and unavoidable. Factors such as context of care setting, environment, privacy, midwifery care, particularly in a continuity of carer model, have considerable positive affect on women’s experience of examinations. Further research into women’s experiences of vaginal examination in different care models as well as research into less invasive intrapartum assessment tools that promote physiological processes is urgently require

In-situ and invasive carcinoma within a phyllodes tumor associated with lymph node metastases

BACKGROUND: Phyllodes tumors (cystosarcoma phyllodes) are uncommon lesions in the female breast. Rarely, the occurrence of carcinoma within a phyllodes tumor has been reported in the literature, but has never been associated with lymph node metastases. CASE PRESENTATION: A 26-year-old woman presented with a firm, mobile, non-tender mass in the left breast and palpable lymph nodes in the left axilla. The excised lesion appeared well circumscribed and lobulated, with variable fleshy and firm areas. Microscopic examination showed a circumscribed fibroepithelial lesion with a well developed leaf-like architecture, in keeping with a benign phyllodes tumor. The epithelial component showed extensive high grade ductal carcinoma in-situ (DCIS) and invasive carcinoma of no special type, located entirely within the phyllodes tumor. Subsequent axillary lymph node dissection revealed metastatic carcinoma in four lymph nodes. CONCLUSIONS: Although rare, phyllodes tumors may harbor DCIS and invasive carcinoma, with potential for lymph node metastasis
